Specification of Illetters Patent.

Application filed December 14, 1908. Serial No. 467,435.

To all whom it may concern: V

Be it known that I, ALEXANDER S. Kronor, a citizen of the United States,residing at Great Falls, in the county of Cascade and State of Montana,have invented certain new and useful Improvements in EducationalDevices, of which the following is a specification, reference being hadto. the accompanying drawings.

This invention relates to improvements in educational devices and moreparticularly geographical globes. a.

The object of the invention is to provide a device of this charactervcomposed of separable sections which when separatedmay be nested topermit them to be packed and shipped at a small expense and which may bequickly and easily put to ether and set up for use, a further object 0the invention being to provide a device of this character which isinexpensive in construction and at the same time strong and durable.

With the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation of ageographical globe constructed in accordance with the invention; Figs. 2and 3 are detail longitudinal sections through the two semi sphericalsections or shells; Fig. 4 is a detail view of the pivoted hook orclamp; Fig. 5 is a detail view of one of the eyes to receive the axis orsupporting rod; Fig. 6 is a detail sectional view through portions ofthe two globe sections showing the arrangement of the overlapping eyesto receive the axis or supporting rod; Fi 7 is a detail sectional viewshowing one 0 the pins and its keeper loop for holding the edges of theglobe sections in proper alinement or register; Fig. 8 is a detailperspective of the keeper loop shown in Fig. 7 and Fig. 9 is a detailsectional view through a portion of the axis or supporting shaft showingone of its springs catches.

In the drawings 1 and 2 denote two similar semi-spherical shells whichform the sectional globe, the same being detachably connected andremovably mounted upon a supporting rod or axis 3. The latter isdisposed at the usual inclination and projects from a suitable support 4here shown rising from a base or stand 5. The supporting rod or axis 3may be constructed of wood, metal or other material and in it arearranged suitable catches 6 to retain the globe upon it and at the sametime allow for the free rotation of the globe. Two of said catches 6 arepreferably provided and, as clearly illustrated in Fig. 9, each consistsof a lever pivoted at one end, as shown at 7 and having a portion toswing into and out of a longitudinal slot 8 formed in the rod 3. Saidportion of the lever has an intermediate recess 9 to form a seat for theedges of the two globe sections or shells and on opposite sides of saidrecess 9 are inclined edges 10 which lead up to said recess. A spring 11bears against the inner edge of the catch lever 6 to project its notchedand inclined portions through the slot 8 in the rod.

While the globe may be divided on the line of the equator, it ispreferably divided on the line of one of the meridians of longitude, andas illustrated in Fig. 1, to separate the globe. into the eastern andwestern hemispheres. To detachably fasten the two halfsections or shellsoverlapping eyes 12, 13 are provided at the upper ends of the same.These eyes are in the form of apertured metal plates set in and suitablysecured to the half-sections 1, 2 with their apertures or openings inregister with oppositely disposed notches 14 formed in saidhalf-sections so that when the latter are placed together, as shown inFig. 6, the'rod 3 may be readily passed through the registering openingsand notches. At the lower end of the globe one half-section has asimilar apertured plate or eye 15 while the other has a clasp 16preferably in the form of a pivoted hook, the pivot portion 17 of whichextends through said half-section so that the hook 16 is disposed uponthe inside of the globe while the finger plece 18 of the clasp or catchis upon the outside, as clearlyshown in Figs. 1 and 2 of the drawings.For the purpose of keeping the edges of the half-sections or shells inproper alinement or register pins 19 are provided at diametricallyopposite points on one of the half-sections to enter keeper loops 20arranged at corresponding points on the other half-section. Any numberof said pins 19 and loops 20 may be arranged around the edges ofthe'half-sections but, as illustrated, only two are provided and theyare arranged at points mldway the poles of the globe.

It will be understood that the sections of the globe may be made ofcardboard, pressed paper, wood fiber, or any other light and inexpensivematerial and that the map of the world on the outside of the globe maybe complete or partially complete according to the purpose for which theglobe is designed.

In assembling the parts, the section 2 of the globe is first placed uponthe support by passing the rod 3 through the apertured plates or eyes15, 13 and until they spring into the seats 9 of the spring catches 6.The apertured plate or eye 12 of theother section 1 is then slipped overthe end of the rod and when it engages the section 2 the lower end ofthe section 1 is swung outwardly sufiicient to permit the pins 19 toenter the keeper loops 20, whereupon, said section 1 is swung againstthe section 2 so that the edges of the two sections will be flush witheach other. The finger piece 18 of the hook or clasp 16 is then turnedto cause the hook to engage the rod and thereby effectively retain thehalf-sections together, the catches 6 retaining them upon the rod and atthe same time allowing them to retate freely.

From the foregoing it will be seen that the invention provides anexceedingly simple device of this character, the partsof which may beproduced at a small cost and may be quickly and easily put together ortaken apart. When separated the globe sections may be nested or put onewithin the other so that they will occupy but little space and may,consequently, be easily stored or shipped at small expense.

Having thus described the invention what is claimed is:

1. A device of the character described comprising a supporting rod, arotatable globe removably arranged on said rod and composed of separablesections and overlapping eyes upon the edges of the sections of theglobe to receive said supporting rod! 2. A device of the characterdescribed comprising a supporting rod, a sectional globe, overlappingeyes on the edges of the sections of the globe to receive said rod andmeans for retaining the globe on the rod.

3. A device of the character described comprising a supporting rod, asectional globe, overlapping eyes on the edges of the sections of theglobe to receive said rod, and

a spring catch for retaining the globe upon the rod;

4. A device of the character described comprising a supporting red, aglobe comosed of separable half-sections, alining eyes ormed atdiametrically opposite points on the edge of one half-section of theglobe, said eyes being adapted to receive the rod, an eye upon one pointof the other half-section adapted to also receive said rod and a claspdiametrically opposite said eye on the last mentioned section of theglobe for retaining the sections together and upon the rod.

5. A device of the character described comprising a supporting rod, aglobe composed of separable half-sections, alining eyes formed atdiametrically opposite points on the edge of one half-section of theglobe, said eyes being adapted to receive the rod, an eye upon one pointof the other half-seetion adapted to also receive said rod and a pivotedhook diametrically opposite the eye on the last mentioned section of theglobe, said'hook being adapted to engage the rod.

6. A device of the character described comprising a supporting rod, aglobe composed of separable half-sections, alining eyes formed atdiametrically opposite points on the edge of one half-section of theglobe,

said eyes being adapted to receive the rod,

an eye upon one point of the other half-section adapted to also receivesaid rod, a fastener diametrically opposite the eye on the lastmentioned section of the globe, for holding said sections together andmeans for retaining the globe upon the rod.

7. A device of the character described comprising a supporting rod, aglobe composed of separable sections, eyes upon the edges of thesections of the globe at opposite points to receive said rod, pins uponother points of the edge of one of the globe sections and keeper loopsor eyes at corresponding points on the edge of the other globe sectionand adapted to receive said pins to retain the meeting edges of theglobe sections in register or alinement.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
